The GE 44-ton switcher is a 4-axle diesel-electric locomotive built by General Electric between 1940 and 1956. The locomotives were available with a choice of prime movers. Most were built with a pair of Caterpillar Inc.'s D17000 V8 180 horsepower (134 kW) engines. It was designed for industrial and light switching duties, often replacing steam locomotives that had previously been assigned these chores. This locomotive's specific 44-short ton weight was directly related to one of the efficiencies the new diesel locomotives offered compared to their steam counterparts: reduced labour intensity. In the 1940s, the steam to diesel transition was in its infancy in North America, and railroad unions were trying to protect the locomotive fireman jobs that were redundant with diesel units. One measure taken to this end was a stipulation that locomotives weighing 90,000 pounds (41,000 kg) or more required a fireman in addition to an engineer. The 44-ton locomotive was born to skirt this requirement. Other manufacturers also built 44-ton switchers of center-cab configuration. 348 examples of this locomotive were built for North American railroads. Many remain, in service and in museums.
Recorded from a GE 44-Tonner
This project is a normal idle version. It is an air throttle version. It has a single exhaust stack.
File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual notching. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.
Prime mover volume selection mode. By default the prime mover has volume dynamics. Meaning idle is soft while notch 8 is loud. This is very prototypical. The next option is volume maxed out. Meaning idle and notch 8 are the same volume. This is more suitable for people who like it loud.

Auto Bell:
Many Second and Third Generation locomotives have been fitted with an Automatic Bell that is triggered when the horn is blown. In MANY cases this cannot even be bypassed on modern locos. Before the FRA mandated this feature on new locomotives the bell was of course turned on and off separately. Some locomotives were delivered with a manual bell and have been converted to an automatic bell. This creates a challenge in sound file creation.
We realize that not every loco with a particular prime mover had this feature. As such we have built in an option to turn the feature on and off. We will set the default in the file to be what is most appropriate for the particular file.
To turn the feature OFF - Auto Bell OFF:
1. Remove the Auto bell sound slot from the function mapping chart

2. Change the sound configuration of the Auto bell sound slot

The ALCO 251 prime mover was the most popular and abundant prime mover ever made by the company. While it proved to be quite successful, it sadly outlived its original manufacturer. ALCO closed their doors in 1969. The 251 prime mover is actually still available to purchase today from Fairbanks Morse for use in marine, generator and locomotive uses.
Our recording is from a 16cyl 251C and could be found in the following locomotives:
C425, C628
Other locomotives using variations of the 16cyl 251 prime mover included:
RS27, C424, C430, RSD-15, C630, C636, WDM-2 (Indian Railways)

The 251 prime mover is actually still available to purchase today from Fairbanks Morse for use in Marine, Generator, and locomotive uses.
The 1500 horsepower 8cyl version of the 251F could be found in the following locomotives:
C-415
The C415 was a large switcher or small road switcher equipped with a raised cab mounted slightly off-center, with a lower, narrower hood on either side. The longer one contained the diesel engine, a 1,500 hp (1.1 MW) eight-cylinder turbocharged Alco 251-F, while the shorter contained auxiliaries. The C415 could be ordered with three different cab heights; a low one for minimum clearances, a regular height one, and an extra-height one for maximum visibility.
Trucks fitted were either Type B road trucks or ALCO Hi-Ad (high adhesion).

GE Evolution 12cyl "GEVO" Locomotives have a 4 stoke diesel engine and have been designed to be more efficient and more emission friendly than previous models. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference, though admittedly there is little sound difference if any between the two.
All early GEVOs were delivered with the Nathan Airchime K5HL air horn. Later GEVOs started to recieve a slightly different K5HLL horn. Most if not all have been delivered with a Graham-White 373 E-Bell. This E-Bell is tied to the horn circuit in the locomotive and will play automatically when the horn is played. The ESU version also has this new feature. The bell can be activated by either pressing F1 or by pressing the horn using F2. The "Auto-Bell" can be turned off by removing the the Auto-Bell sound slot from F2.
Another feature of the prototype is "Smart Start". For the sake of both emissions and fuel savings all GEVOs have been built with an auto shutdown/auto start feature. After the loco has been idle for a period time, the engine will shut down on its own. If the prime mover cools to a certain temperature the loco will automatically start again to keep from freezing.

In the Mid 1980s GE changed it's 16cyl FDL design to include a different exhaust silencer, a new electric compressor often known as the "Whoop compressor" and changed some of the electronics of their locomotives. These differences among a few other led to a distinct change in the sounds from the GE 16cyl FDL often found from the U25Bs on through the Dash-7 series of the Locomotives.
GE's AC series of locomotives were introducted in 1994. They share the same carbody design and many of the internal components as the Dash-9 series, except they are equipped with AC traction motors instead of the conventional DC versions. The cab air conditioner was moved from the left (conductor's) side walkway to a position under the cab floor to make space for the six traction inverters (one per axle) that supply the AC current to the traction motors.
The "Modern" GE 7FDL 16Cyl Prime mover can be found in the following Locos:
Dash 8-39B, Dash 8 40-B, Dash 8-40BW, Dash 8-39C, Dash 8-40C, Dash 8-40CM, Dash 8-40CW, Dash 8-41CW, Dash 8-44CW, Dash 9-40C, Dash 9-40CW, Dash 9-44CW, C38EMi, C38AChe, AC4400CW
Some AC6000CW were built with 7FDL-16cyls and were later converted to 7HDL-16cyl. Some were never converted. Please refer to the prototype for reference.
Passenger Locos including: P40DC, and P42DC were built slightly different and contained HEP.
Recorded from a GE AC4400CW
This project has an automatic low & high idle. It has a single late (silenced) exhaust stack.
File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual notching. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.
Prime mover volume selection mode. By default the prime mover has volume dynamics. Meaning idle is soft while notch 8 is loud. This is very prototypical. The next option is volume maxed out. Meaning idle and notch 8 are the same volume. This is more suitable for people who like it loud.

Auto Bell:
Many Second and Third Generation locomotives have been fitted with an Automatic Bell that is triggered when the horn is blown. In MANY cases this cannot even be bypassed on modern locos. Before the FRA mandated this feature on new locomotives the bell was of course turned on and off separately. Some locomotives were delivered with a manual bell and have been converted to an automatic bell. This creates a challenge in sound file creation.
We realize that not every loco with a particular prime mover had this feature. As such we have built in an option to turn the feature on and off. We will set the default in the file to be what is most appropriate for the particular file.
To turn the feature OFF - Auto Bell OFF:
1. Remove the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8
----------------------

2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1

The American Locomotive Company's model 244 prime mover was developed during the mid-1940s to power its post-war diesel locomotives. Interestingly, while Alco helped pioneer diesel technology dating back to the 1920s it had difficulty truly competing against Electro-Motive-Division due to reliability issues with its diesel engines. Before Alco began implementing the 244 in its locomotives the builder had spent most of the 1930s developing an earlier model that was used in most of its early switchers. The new prime mover was supposed to usher in a new era for Alco but instead saw it slip further behind EMD in the marketplace. During the early 1950s the manufacturer replaced the engine with the more reliable 251 that powered its Century series. It would prove to be the company's last engine as it exited the market before 1970.
This sound file would be appropriate for the following locomotives:
RS-2, RS-3, RSC-2, RSC-3, RSD-4, RSD-5
Although there are slight differences, this sound file could also be used in the following locomotives:
FA-1, FB-1, FA-2, FB-2, FPA-2, FPB-2

The ALCO 251 prime mover was the most popular and abundant prime mover ever made by the company. While it proved to be quite successful, it sadly outlived its original manufacturer, ALCO who closed their doors in 1969. The 251 prime mover is actually still available to purchase today from Fairbanks Morse for use in Marine, Generator, and locomotive uses.
The 1800 horsepower 12cyl version of the 251B could be found in the following locomotives:
RS-11, RSD-12, RS-18, RS-36, FPA-4, FPB-4, RSC-14, FD-6, FD-7, FD-9, RSD-16, DL-560, 44 Class, 930 Class
The 2000 Horsepower 12cyl 251C version was extremely close to 251B in the way that is sounded. While we have full intentions to record this in the very near future the 251B is a very suitable substitute. The 12cyl 251C can be found in the following Locomotives:
RS-32, C420, M420, M420B, M420R, M420TR, HR-412, M424, 45 Class, 442 Class, 600 Class, 700 Class, A-321

The EMD 645 family of diesel engines were designed and manufactured by the Electro-Motive Division of General Motors. The 645 series was an evolution of the earlier 567 series and a precursor to the later 710 series. The 645 series engines entered production in 1965. All 645 engines utilize forced induction, with either a Roots blower or a turbocharger. The 645 series has a maximum engine speed of between 900 and 950 revolutions per minute (rpm), an increase over the 800 to 900 rpm maximum speed for the 567 series.
While only a few operating examples exist today, the 20cyl 645E3 was often found in the following locomotives:
SD45, F45, FP45, SD45X, SDP45, SD45T-2, SD45-2, and others

EMD 16-645E3B LATE EXH T HEP H0 N XL L M4
- Article numbers:S0530

- Manufacturer: ESU
The EMD F40PH is a four-axle 3,000–3,200 hp (2.2–2.4 MW) B-B diesel-electric locomotive built by General Motors Electro-Motive Division in several variants from 1975 to 1992. Intended for use on Amtrak's short-haul passenger routes, it became the backbone of Amtrak's diesel fleet after the failure of the EMD SDP40F. The F40PH also found widespread use on commuter railroads in the United States and with Via Rail Canada.
The design of the F40PH was based on the EMD GP40-2 freight locomotive and shared that locomotive's turbocharged EMD 645E3 V16 cylinder, two-stroke, water-cooled diesel engine (prime mover).
For passenger service the F40PH has another electrical alternator, the head-end generator. The HEP unit generates three-phase AC power at 480 V (500 kW on the first order, 800 kW on later units) for lighting, heating and air-conditioning the train. Originally, F40PHs powered the HEP alternator from the prime mover; from the head end to the train must be a constant frequency, and the prime mover had to turn at a constant 893 RPM while supplying head end power (even standing still, with the throttle in idle). Power to the traction motors was controlled by varying the field excitation of the main (traction) generator.
The designation "F40PH" stood for the following: "F" for the full-width cowl carbody, "40" as the locomotive is part of EMD's 40-series (based on the GP40-2 freight locomotive), "P" for passenger service, and "H" for head-end power.
This 16cyl 645E3B W/HEP sound file would be appropriate for the following locomotives:
F40C, F40PH, F40PHR, F40PH-2, F40PH-3, F40PH-2D, F40PHM-2, F40PHL-2
Recorded from a F40PHR
This project is a special isolation switch based high idle version. It has a single turbo late (silenced) exhaust stack.
This file has a Special feature providing the sounds and operation of the Head End Power unit. This is used on the prototype loco to provide electricity to the coaches as these locos are almost always used in passenger service.
To engage HEP you must be stopped in Idle. Pressing F26 (Shift 2) will engage the HEP unit and allow the prime mover to run at a higher RPM.
When in stations often the engineer will go into Standby mode to preserve fuel and to allow the noise levels to come down a little. Pressing F27 on the throttle once HEP has already been engaged will allow the prime mover to come down a little. Again this can only be done while sitting still as on the prototype there is not enough RPM to provide power to the coaches and traction motors at the same time in Standy Mode.
File also contains a "Normal Idle" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to go to "high idle" and begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
You can use F26 and F27 for manual notching. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.
Prime mover volume selection mode. By default the prime mover has volume dynamics. Meaning idle is soft while notch 8 is loud. This is very prototypical. The next option is volume maxed out. Meaning idle and notch 8 are the same volume. This is more suitable for people who like it loud.

Auto Bell:
Many Second and Third Generation locomotives have been fitted with an Automatic Bell that is triggered when the horn is blown. In MANY cases this cannot even be bypassed on modern locos. Before the FRA mandated this feature on new locomotives the bell was of course turned on and off separately. Some locomotives were delivered with a manual bell and have been converted to an automatic bell. This creates a challenge in sound file creation.
We realize that not every loco with a particular prime mover had this feature. As such we have built in an option to turn the feature on and off. We will set the default in the file to be what is most appropriate for the particular file.
To turn the feature OFF - Auto Bell OFF:
1. Remove the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8

To turn the feature ON - Auto Bell ON:
1. ADD the Auto bell sound slot from the function mapping chart

2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1

Auto Bell Timer:
The Bell timer is amount of time the bell will play after the horn if the auto timer is active. The timer is broken down into 1/4 of a second increments.

The ALCO 251 prime mover was the most popular and abundant prime mover ever made by the company. While it proved to be quite successful, it sadly outlived its original manufacturer, ALCO who closed their doors in 1969. The 251 prime mover is actually still available to purchase today from Fairbanks Morse for use in Marine, Generator, and locomotive uses.
The 12cyl 251C can be found in the following Locomotives:
RS-32, C420, M420, M420B, M420R, M420TR, HR-412, M424, 45 Class, 442 Class, 600 Class, 700 Class, A-321
The 2000 Horsepower 12cyl 251C version was extremely close to 251B in the way that is sounded. The 1800 horsepower 12cyl version of the 251B could be found in the following locomotives:
RS-11, RSD-12, RS-18, RS-36, FPA-4, FPB-4, RSC-14, FD-6, FD-7, FD-9, RSD-16, DL-560, 44 Class, 930 Class
The 12cyl 251 was also used in many rebuilt locomotives including:
RS-3m, C424m, and others...
Recorded from a ALCO C-420
This project is a normal idle version. It has a single exhaust stack.
File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual notching. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
